   Reason analyze:
   
   **jpa code:**
   debug info:
   class:Loader.java
   method:processResultSet
   
   **this rs.next() call two times,  result list size is two，finally jpa throw 
error；**
   rs：ShardingResultSet   call    IteratorStreamMergedResult
   
   
   ```
   for ( count = 0; count < maxRows && rs.next(); count++ ) {
                        if ( DEBUG_ENABLED ) {
                                LOG.debugf( "Result set row: %s", count );
                        }
                        Object result = getRowFromResultSet(
                                        rs,
                                        session,
                                        queryParameters,
                                        lockModesArray,
                                        optionalObjectKey,
                                        hydratedObjects,
                                        keys,
                                        returnProxies,
                                        forcedResultTransformer
                        );
                        results.add( result );
                        if ( createSubselects ) {
                                subselectResultKeys.add( keys );
                                keys = new EntityKey[entitySpan]; //can't reuse 
in this case
                        }
                }
